| Research Abstract |
Star-shaped polymers with many arms may function as" molecular flasks," as their structures can be multi-layered. In order to realize effective reactions fields, star polymers with multiple components should be precisely synthesized. In this study, innovation strategies for precision star polymer synthesis of star polymers were achieved using base-assisting living cationic polymerization. Facile one-step synthesis of star polymers based on monomer-selective domino living polymerization of a vinyl ether and a divinyl compound with alkoxystyryl moieties can be achieved using an EtAlCl_2/ SnCl_4 initiating system. Well-defined star polymers were also synthesized by a core-first method, in which a microgel core was first prepared. Heteroarm star polymers were prepared by simple mixing of a couple of living polymers with a divinyl compound.
